The clock tower stands in the centre of the Plaça de la Vila de Gràcia and, at almost 33 metres high, is the tallest public tower in the district. Although it is built mainly of stone ashlars, brick was used for the construction of the windows that open out, the vertical bands that decorate it and the corners of the structure. The tower has a solid square stone base, topped on each side with the coats of arms of the Vila de Gràcia, Barcelona, the Principality of Catalonia and the arms of Queen Isabella II. In the keyhole of the base facing the City Hall building, there is a fountain, framed by a large arch and with two sculpted spouts in the shape of faces that spout water from their mouths. On the upper part of the fountain, also framed by the arch, is a commemorative plaque commemorating the year of its construction (1864), the damage it suffered during the popular uprising of the “Quintes” in 1870 and its restoration in 1882.

The body of the tower itself is built on the square base. It is octagonal in plan, although the eight faces are not of a unitary size; rather, those that make up the corners are smaller and projecting, more like a kind of chamfer. For this reason, the windows that open onto the tower are only on the four main faces, which coincide with those of the square on the ground floor. The tower is organised in elevation on three clearly differentiated levels, the first of which runs directly on the square podium and is topped by a large cornice. This cornice is decorated with twelve sculpted plaques representing the zodiac, which are the most emblematic element of the tower, making it the only civil tower in the Vila de Gràcia (the rest were church bell towers).

The next section, which is higher than the previous one, has two groups of windows that are configured as small openings in sardinel brickwork and are framed by the vertical brick strips that decorate the tower. These strips extend to the cornice that closes this second body and are finished off with a kind of arches reminiscent of those found in Romanesque mountain constructions. This cornice, which separates the second part of the tower from the crowning, develops in the form of a continuous cantilever, giving rise to a circulation element that surrounds the top floor. This continuous balcony with an iron railing makes sense because of the structure of the building itself: a bell tower with a clock.

On the top floor there is a clock with four dials that can be seen from any point in the town. The machinery was built by the Swiss watchmaker Albert Billeter, the true precursor of electric clocks in Spain. The structure is crowned by a large bell, the work of Isidre Pallarès, decorated with elaborate friezes, the coat of arms of Gràcia and reliefs of Saint Isidore, the Virgin of Gràcia and the Blessed Sacrament.

On the ground floor, there is a door that leads to the inside of the tower, where there is a spiral staircase with a continuous return and without landings that leads to the clock machinery.
